We received our 400W Solarstorm grow light 3 weeks ago and immediately put it up into our bloom room along side our 600W HPS hoods/lights. I must say the the plants took off and surpassed other plants that were 2 weeks ahead of them. This was a wonderful surprise. If the LED lights cost a little more but produce this well, while decreasing the electric bill, then they are well WORTH THE COST!
I will report back before harvest.
